The UCI has issued rules this year against the use of studded tires for cyclocross competitions. Reports say that UCI had decided to put these regulations into place after rumors circulated about cyclocross star Sven Nys using new Dugast tires with embedded metal spikes, called the ‘Diabolo‘.
The new UCI regulations (1.3.018) specifically state that “For the cyclocross bicycle… the tire shall not exceed 35mm and it may not incorporate any form of spike or stud.”
News reports from Belga said that the Dugast spiked tires had been tested by Sven Nys in icy conditions in The Netherlands, and that the ‘Diabolo‘ tires had performed extremely well with excellent grip. The Belgian cyclist himself had reportedly proclaimed the tires as “phenomenally good” after the tests.
The UCI ban comes into effect in time for the approaching Cyclocross World Championships in Tabor, Czech Republic. The event will be held on an icy course that has been frozen solid by temperatures reaching sub-zero degrees, so bicycles with spiked tires would have had the upper-hand in terms of handling and control.
